Seminar: “Modelling DC-Induced Nonlinearity in Optical Fiber” – Chris Sapiano
CREOL 102
Monday, September 12, 2011 / 11-12pm

Abstract:
Silica glass, owing to its inversion symmetry, does not exhibit even ordered nonlinear susceptibilities. However it has been observed that heating and cooling a glass sample under the influence of a DC electric field (a process known as thermal poling) a significant second order nonlinearity can be induced. This talk will outline work towards modelling these DC-induced nonlinear processes in fiber. There will be specific focus on providing balanced comparisons between DC-induced processes and their equivalent third order processes.
Bio:
Chris Sapiano received a B.A.Sc. degree with honors from University of Toronto in Engineering Science (physics option). During his undergraduate thesis research he worked under Prof. Li Qian on the design and construction of erbium doped fiber laser systems for use in passively mode-locked laser systems. Following this he fast-tracked into the PhD program in Electrical Engineering as a member of the Photonics Group. His research, supervised by Prof. Stewart Aitchison and Prof. Li Qian, has focused on simulation of various aspects of nonlinear generation in thermally poled silica fibers.
